Los Angeles County, not Diamond Bar
Los Angeles County context, not Diamond Bar figures
These are Los Angeles County figures. There is no place level equivalent published for any of them, so they are shown as the county backdrop and never as Diamond Bar measurements.

- Employment at those establishments, Los Angeles County3,987,736
- Covered employment, Los Angeles County4,525,711

Every figure in this section is published for Los Angeles County as a whole and is not a measurement of Diamond Bar. It is here because a county backdrop is what a credit committee reads a place against, and it is labelled so that it can never be quoted as the place's own.

Coverage
What this page does not hold.
Every item below could be filled with a plausible figure. None of them is. On a page a lender may read, a number that cannot be traced is worse than an absence, so the absences are named.
- Parcel level detail, zoning and flood zone at an address are resolved in the platform, not on this page.
SBA figures count approvals to borrowers whose address is in the place. They are not approvals for projects inside the place boundary: the tape records a borrower city and a project county, and those can differ.
Common questions

How much SBA lending goes to Diamond Bar businesses?
71 7(a) approvals totalling $39.9 m, across 26 lenders, median approval $284,000, plus 23 504 approvals worth $24.4 m. These count approvals to borrowers whose address is in Diamond Bar, not projects sited inside the place boundary, and they are approvals recorded in the release rather than loans disbursed.
Do SBA loans to Diamond Bar borrowers get paid back?
Of the 15 loans that have reached a final outcome, 12 were paid in full and 3 charged off, a charge off rate of 20.0 percent. Loans still running are excluded because they have not yet succeeded or failed.
Is Diamond Bar in the National Flood Insurance Program?
Yes. Diamond Bar appears in the FEMA Community Status Book as community 060741, with no Community Rating System class, so no CRS discount applies. Whether a specific parcel sits in a mapped special flood hazard area is an address level question the platform answers.
Are the county figures on this page Diamond Bar figures?
No, and they are labelled so. County Business Patterns, QCEW, the Building Permits Survey, BEA product and IRS migration are published for Los Angeles County as a whole and there is no place level equivalent. They appear in one clearly marked section as context and are never presented as measurements of Diamond Bar.
Is zoning published for Diamond Bar?
Not yet. The zoning layer is in build. Nothing on this page presents parcel level zoning.
